For 240 bucks, I could always use a spare. But I'm wary.

As I thought. Too good to be true.

Always worth a try I suppose.

Thanks for the advise and sorry it took me so long to get back but I had to go out of town for a few days. It turned out to be the PROM which had gone south. I had a Hiabeck PROM from several years ago before some engine work. We plugged it in and the poor running issues vanished. The old girl is back and bad assed! I did find a used ECM but the seller couldn't tell me a thing about it other than it came out of a running ZR. I also found that Volunteer Corvettes offers refurbishing services for our ECM.

You all did come through for me again and I can't say how much I appreciate you!! Thanks!

Been suspecting I might have a problem with my ECM too on my 1991. Do you guys know if Marc Haibeck would be able to check if my ECM is OK if I send it too him?

It is a little pricey at $800, but there is an ECM on ebay right now.
An old stock refurbished part from AC Delco.

But if you absolutely need one, you don't have a lot of choices.

Hi all,

I had an ECM failure in my car a few months ago. Radiator fans would come on with key in ignition, car would start but would die unless giving it gas. Sent my ECM to Marc and he confirmed the ECM was dead. Sent emails to a few companies who offered a ZR1 ECM repair service but did not hear back from any (maybe given I live in Australia). I ended up finding one in the USA by positing a wanted add on this forum. Plugged it in and she fired right up (was a big relief). Good luck with your search!

How about installing a mega squirt ecm in the car, like some forum members did.
If that works proper it’s a replacement for our ecm’s ?
